The injured man has been identified as 20-year-old Romario Jn Baptiste of Lastic Hill, Castries.
It is alleged that the vehicle was being returned to its owner when the accident occurred. However, a source said the driver was not the person who rented the vehicle.
“He dropped the person who rented the jeep at the airport and he was taking it to the owner,” the source alleged.
An eyewitness told St. Lucia News Online that the owner of the vehicle appeared upset that someone else other than the person who rented the vehicle was driving.
It is not yet clear how many people were on board the Terios when it overturned and if the driver was the injured person.
Police are investigating.
